Introduction

development of a battery-operated dual-function agricultural machine designed to improve efficiency for small-scale farmers by combining cutting and pesticide spraying in a single operation. Traditional farming methods are slow, labor-intensive, and often rely on costly and polluting petrol-powered machines. This project addresses those issues by using a 12V battery-powered system, making it eco-friendly, low-cost, and suitable for small landholdings.

The machine is built on a mild steel L-angle chassis and includes a 775 DC motor with a cutting blade and a diaphragm pump for pesticide spraying. Both systems operate simultaneously: the motor cuts vegetation while the pump sprays pesticides through nozzles in one forward motion. Power is controlled using a PWM controller and a 12V battery system, enabling efficient and smooth operation.

Field testing showed the machine can cut a 14-inch swath at about 10,000 RPM while spraying pesticide at 100 PSI with a 1.2-meter coverage, operating for 35–40 minutes per charge. Structural improvements reduced vibration and improved stability.
